Synopsis

She got transported into a game — not as the hero, but as the Demon Lord at level 999. Simply for being born a Demon Lord, she spent ten years locked away by her own family before being exiled to the frozen wastelands of the north. But if magic can conjure a greenhouse, maybe she can quietly farm her way through a peaceful, low-key retirement. Unfortunately, the story's male lead candidates keep barging in uninvited and wrecking all her plans for a simple life.
